Halter yellow. Abdomen yellow. Male sternite 5 with concave distal border. Genitalia (male) (Figs 20–24): Protandrium semicircular, 7th spiracle without surrounding setulae; surstylus basalyy fused with epandrium, apically furcate with an outer and an inner processes; hypandrium without distinct apodemes, gonopod long and pointed apically; aedeagus long, pointed apically, with narrow apical incision. Type material. Holotype male deposited in CAU, Guizhou: Fanjingshan Mountain (27°55'N, 108°41'E) (21002200 m), 2002. V. 31, Ding Yang. Paratypes 15 males 10 females, same as holotype; 3 males 4 females, Guizhou: Fanjingshan Mountain (27°55«N, 108°41'E) (18002200 m), 2002. VI. 1, Ding Yang. Remarks. The new species is somewhat similar to Homoneura (Homoneura) grandis (Kertész, 1915) from Taiwan, but can be easily separated from the latter by the surstylus with the pointed tip. In grandis, the surstylus is rounded at tip (Malloch 1929). Etymology. The species is named after Prof. Maofa Yang. Distribution. China (Guizhou).
